IPC: H03H19/00
Filed: 1990-04-02
Abstract: PURPOSE:To realize a filter of a video band whose circuit integration has been difficult so far by devising a transistor(TR) circuit so that its gain and its cut-off frequency both depend on a capacitance ratio. CONSTITUTION:A differential amplifier is formed by two TRs Q1, Q2 whose characteristics are identical to each other in this low pass filter. The emitter of the TRs is connected to a low current load 1 (2) respectively. Emitters of both the TRs are connected through the switch 3a of a switched capacitor 3. Through the constitution above, a gain Ga of the circuit is expressed as Ga=C3/C4 and its cut-off frequency fc is expressed in equation. That is, since both gain and the cut-off frequency are dependent on the capacitance ratio, the circuit is suitable for circuit integration.

Title: Blood storage tank
Inventor: NOGAWA ATSUHIKO
IPC: A61M1/14
Filed: 1991-03-27
Abstract: PURPOSE:To check the generation of bubbles by making an upright tube part of a tube body in a heat exchanger orthogonal to an internal wall of a housing through which blood flows down to reduce the entrainment of air in the collision of the blood against a tube body, regardless of a decrease in the amount of blood storage even when the tube body is exposed in the air. CONSTITUTION:Blood flowing into a housing 2 from a blood inflow port 6 of a blood storage tank 1 is defoamed with a defoaming member 8 to be stored into a blood storage space 5, along an inclination part 32 on an internal surface of a protrusion 31 formed on a housing body 3. Blood at the upper part of the blood storage space 5 flows down, passing through a clearance or the like between tube bodies 10 at a heat exchanger 9, reaching a lower space 51, and then, flows out of a blood outflow port. On the other hand, a heat medium flows into a heat medium chamber 16 at a heat medium inflow port, undergoes a heat exchange with the blood passing through the pipe bodies 10, and then, flows out at the heat medium outflow port via a heat medium chamber 17. At this point, since the pipe bodies 10 are orthogonal to an inclined surface 32, there is a reduction in the entrainment and bouncing of air even when the blood collides against the tube bodies 10, thereby enabling the checking of the generation of bubbles.
